Porsche wowed automotive enthusiasts when it unveiled
the 918 Spyder nearly a year ago. Porsche made those who can
actually afford the vehicle salivate when it announced that it would
actually make a production version of the vehicle.
Today, Porsche revealed its racing
variant of the vehicle: the 918 RSR. The 918 RSR takes the best of the 918
Spyder (its sexy shape, albeit in coupe form) and combines it with the
flywheel-based hybrid system found in the 911
GT3 R Hybrid.
Like the 918 Spyder on which it's based, the 918 RSR uses a
3.4-liter V8 that develops 563hp at an incredible 10,300rpm. The vehicle
also features a 36,000rpm kinetic energy recovery system (KERS) flywheel
actuator that stores energy generated during braking. With the touch of a
button, the driver can call upon two electric motors (one in each front wheel) that use
that stored energy to give a momentary power boost (8 seconds on a full charge)
The electric motor also provide torque
vectoring for improved handling and steering response.
to AutoWeek, Porsche has plans to
produce a version of this concept for the racetrack, and a production model of
the 918 Coupe (minus KERS) will join the 918 Spyder in 2013.
